By 2050, an estimated 10 billion people will live on earth. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change? In a talk packed with wit and wisdom, science journalist Charles C. Mann breaks down the proposed solutions and finds that the answers fall into two camps -- wizards and prophets -- while offering his own take on the best path to survival.

Marshall Banana : I work in a grocery store and every single day, I throw away hundreds of pounds of perfectly good food. My last job was a restaurant job, same exact deal. Most of the food that came to us goes straight into the trash eventually. And yet all I hear about are people saying we don't have enough food to feed 10 billion, that's bullshit. We have so much food we throw away enough to feed 10 billion!

DAMfoxygrampa : We somehow hittin 10 billion but I can't get a text back

Teacher Advice Hanoi : Perhaps y'all should...umm...stop breeding

TerielAtmano : People would protest and share knowledge if they saw the problems in this video as greater than their own personal troubles. No one has time to go to the streets to fight for nuclear energy when they're struggling for enough money, a loving partner, good friends, having time to relax, being skilled at something, getting rid of personal addictions... Until we get better at solving personal problems at a global scale, we won't care about the bigger picture. Universal basic income seems like a good start to free up some personal energy to devote to bigger matters. This might not work either, as it seems like we'll just keep comparing ourselves to each other and finding new personal worries to spend our energy on. Maybe we should study the mindsets of people who made change on a greater scale, and try to create conditions that foster those mindsets on a massive scale.

fxc2 : The cynic in me says that a lot of people are going to be left to die without basic resources while in the wealthy countries almost nothing will really change...

Systematik : Not having kids is my contribution. Stopping the bloodline right here! :-D

ben s : It's telling in the part where he says, "We think we're special, but it's much worse than that", then everybody laughs. You'd think a statement like that would silence everyone, but the irony is we do think we're so special that our individual preservation will always come before a globalised effort to make the changes we need.

Kathy Coleman : In the year 2525 If man is still alive, If woman can survive, They may find...

SuicideBunny6 : Yer a wizard, Harry!

Sean Uptown : Less procreation. Humanity should focus on 4 billion by 2118, 3 billion by 2150. Quality is better than quantity, the first global singularity should be the plan for reduced procreation world wide.

BFDT : At 10 billion, the natural world in so many places will be replaced with our and our slave species biomass. There won't be enough room or resources for any other biomass, except of course, for the bacteria. The bacteria is the predator of 10 billion. Watch.

Fátima Reyes : To me, the solution has always been obvious: educate people. It has been shown that the more educated people are, the less kids they have; the more educated they are, the more money they make and the more aware they are of human problems, and therefore the more willing they are to help solve them.

Sank E : Procrastination will end the human dynasty .

Adam A. : Legend has it, he only blinked once during the whole speech.

Noah Aubrey Linus Sorensen : You’re a wizard, Harry 🧙‍♂️

Quahntasy - Animating Universe : All I am waiting for is *Thanos* Admit it deep in our hearts we know he is not the real villain.

Christopher Ellis : If... I expect it to implode before that figure, because that's what happens in real life nature.

Gas Axe : The wizards are going to boot up 5g soon. This is going to solve the problems of this world.

Jason Vectrex : We will just start wars and kill each other eventually on a grand scale like the old days to free up resources and land, and keep the population down.

Motivação Para Todos : Human race needs Jesus. and i`m atheist.

10000 Subscribers with videos : It will be the almighty *PURGE* Joseph Stalin: am I joke to you Joseph Stalin: hold my vodka

kremit : *_Thanos will save us_*

king spartann : Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?" 67:30( The Glorious Quran)

Steven Martin : Mad Max Beyond the Thunder Dome style gladiator matches? Deathball? DCU movies...? Pick your poison. 😉

Kaustubh Gupta : What a wonderfully well delivered talk... One of the best talks ever..

Dan O'reilly : We need a new plague - Dwight K Schrute

Callum Lueders : WOW. This. video. really. fuucked me up How am i going to argue with a SCIENCE JOURNALIST that he's saying toblerone wrong?!?!?!?! MY LIFES A LIE

AdonaiLove 33 : TAKE that wig

Stuart Porteous : I turned off when he said "TobleronE"

iggy fugazi : technology and consumer usage change example propane we don't need to use propane theri are alternatives...

HESH HUNTER : Give everyone 1.5 acres of the liveable land!?

Beartosser : Fission is a bridge technology while we develop and deploy fusion.

TANGLDWEB : SIMPLE.... SOYLENT GREEN !!! ...pretty easy question actually 😂...

Vincent Sleeves : Wizards only fools. Keep it tight.

Elizabeth Jimenez : This guy is just trying to hoard Toblerone!

rodenrren2 : Is corruption and inequality in Tokyo really that low??

S Blaise : Call Gandalf. He knows the solution ! Great speech, without any pictures or powerpoint what usually people do, I could imagine everything what he said.

Emperor Scott Yee : Don't worry, WW3 or Global Warming will make sure we don't make it to 10 billion. After all, who wants World Peace anyways? Long. Live. Nationalism!

Ed SnowDread : Who else spotted Elizabeth Mitchell (Lost Series) in the crowd?

Deadfrau3 : Our "petri dish" is Mother Eath, and we try to leave it and learn about the cosmos... but in the end it's futile. If we don't have tech to create wind farms, non-leaky pipes and stable nuclear plants... How can we possibly survive in outer space for extended time?

Mass Extinction : No humor 🙄 just tell me wtf you want from me! 😱

schwartzy65 : Should be "how nature will survive"...

HiBrian : "except for possibly tokyo"

Paul Googol : if we can reach, can everybody get an achievement badge?

ano nymous : I have no clue what his point was. Exceptionalism despite all counterarguments? Co-operation between "wizards & prophets" is just delaying the cataclysm not a solution. There are only two relevant paths: human population planning or doom. The first would mean losing the right to reproduce for many and euthanasia being globally accepted. I'm a pessimist. There is no way we can prevent this from ending badly for our species.

Publius Ovidius Naso : Thank you for sharing- I found that very insightful and it has left me contemplating new ideas!

AHG987 : Ai will solve the problem.. one way or another.

Sanguinarius9999 : Sounds like the French watched this TED talk.

Planewalker : Both wizards and prophets are wrong, you need to find the six INFINITY STONES!!!!
